Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed July 28, 1919. Serial No. 313,866.

T o allwhom it may concern Be it known that I, GEORGE MOD. JOHNS, acitizen of the United States, residing at the city of St. Louis, Stateof Missouri, have invented a certain new and useful Improvement inAtomizers, of which the. following is a full, clear, and exactdescription, such as will enable others skilled in the art to which .itappertains to make and use the same, reference being had to theaccompanyforming part of this specification, in which packing jointsexcept at the margins of the r by a spring 10. This plunger carries acome Figure 1 is a side elevational view of my atomizer. I

Fig. 2 is a similar viewpartly in vertical section.

Fig. 3 is a similar view partly in vertical section, and,

Fig. 4 is a cross-sectional view showing the valve operating mechanism.

This invention relates to a new and useful improvement in atomizers foruse in connection with paints, sprays and deodorizers, and the object isto operate the valves which control the air and material by a I valvemechanism which is entirely disconnected from the valves. am enabled touse valves whlch require no operate the valves.

In the drawings, 1 indicates the barrel of the atomizer which at itsforward end'is provided with a nipple 2, the orifice of which is incommunication with an opening 3 passing through the barrel. There is anozzle 4 adjustably arranged On the forward end of the barrel whosechamber communicates with an opening 5 also passing through the barrel.These openings 3 and 5 diverge or pass to opposite sides of the barreland communicate with chambers 6 and 7, respectively, on opposite sidesof the main or body portion ofthewbarrel which has a medial chamber 8in-which is located a manually operable plunger 9 held outwardlydiaphragms which 11 which operates between buttons 12 carried bydiaphragms 13, said diaphrag rns being held in position by skeleton r1ng14 which carries packing glands 15 for the purpose of making a tightjoint with the body portion of the barrel 1.

16 indicates a packing gland bearing against the outer side of skeletonring 14, being interposed between said ring and a In'this manner Iconnection 17 which connection is in the form of a chamber and carries aseat 18 for a valve stem 19, which valve stem carries a valve 20 bearingupon a valve seat formed on the outer face of the skeleton ring 14, thevalve stem 19 extending inwardly beyond the valve and being in reistration with the stem of the button 12 carried by the diaphragm 13.

There is a coupling member 21 threaded on the body portion of the barrel1, which, when. screwed down, holds the connecting *member 17 tightly inany position in which it may be adjustably rotated. The spring 22 tendsto hold the valve 20 to itsseat.

coupling provided with a valve 23 connects, by means of a flexible hose24, with the material or air supply, as the case may be, and thus theingress of these may be regulated.

The rear portion of the barrel terminates in a handle 1 for convenienceof manipulation in order that the spray may be directed to the desiredpoint, this handle being held by the operator and the button on the stembeing manipulated to coincidently operate the diaphragms and the valves20 to allow the air and material to pass through the openings 3 or 5 inthe barrel, as the case may be, where the air will siphon (or blow) thematerial out inthe form of a spray.

While I have shown a cone as constituting the. valve operatingmechanism, it will, of course, be understood that a wedge will serveequally well; also, it will be seen that the springs bearing on eachoppositely disposed valve stem will balance thev cone or wedge in itsmovement so that its operating rod or stem-may pass freely through thehandle. The valves are seated by the pressure of spiral springs withinthe diaphragm inclosed chambers, and hence their operating rods requireno packing.

What I claim is: j

1. An atomizer of the character described comprising two adjustablemembers arranged on each. side of a body portion, diaphragms carryingvalves which control the passageof air and material through 'chambersformed by said members, and valve operating means arranged between saidmembers. 2. An atomizer comprising a barrel portion, a handle portion inline with the barrel portion, valves for controlling the ingress of airand material through chambers on each side of the barrel portion,therebeing a centrally arranged chamber in the barrel portion, and valveoperating means located Within said last mentioned chamber.

3. An atomizer comprising a barrel por tion, a handle portion, providedWith a chamber, valve operating means arranged Within said chamber,diaphragms on each side of said chamber, and valves which are designedto be operated by said valve operating means. u

L. An atomizer comprising a barrel portion and a handle, chambers oneach side of the barrel portionand rotatably adjustable members formingthe outer Walls of said chambers in combination with means for holdingsaid members in position.

5. An atomizer "comprising a barrel portion and a handle, said barrelportion having chambers on each side thereof, ingress tubescommunicating with said chambers,
